Casual music listeners probably only know snippets of that song from television ads for Chrysler and Diet Coke. Or TV dramas like One Tree Hill and 90210. Or the soundtrack to their spinning class.

But an appearance in quirky 2009 rom-com (500) Days of Summer starring Joseph Gordon-Levitt and Zooey Deschanel, was really the perfect, hit-making moment.

"We were able to feel the direct result of that," Temper Trap bassist Jonathon Aherne says, reflecting on the moment that the song took off. "That movie came out pretty quickly ... It was quite exciting for us, and I think we decided not to be precious about how our music got heard.

"When [fans] tell us how they got to know the band, it's through all these different forums, and it's done us a lot of good," Aherne adds. "Probably just now, people are sort of going, 'Hey, you may have done too much.' Maybe we have. But you know, we don't really care."

If some have wearied of "Sweet Disposition," the members of the Temper Trap are not among them. "As soon as you play it, there's this reaction from the audience," the bassist explains. "There are some songs you get tired of playing. But as soon as we play that song, it takes on a life of its own ... It's fun to play for that crowd reaction."
